helpers
This module contains several helper-functions that should make building web applications with Golang easier.
GetExtension
GetExtension parses the given string, by taking everything before the optional question-mark (?), then taking everything after the last dot. If there is no extension in the filename, this function will return the entire filename (without parameters).
ExtractFilePath
ExtractFilePath extracts the path (directory), name (without extension) and extension. The parameters (after '?') are stripped entirely.
GetStringArray
GetStringArray allows easy parsing of context string-array values.

Functions ¶
func ExtractFilePath ¶
ExtractFilePath goes from "https://aa.bb/abc/def.ghi?jkl=mnp&qrs=tuv" to ("abc/", "def", "ghi")
func GetExtension ¶
GetExtension goes from "https://aa.bb/abc/def.ghi?jkl=mnp&qrs=tuv" to "ghi"
func GetStringArray ¶
GetStringArray tries to retrieve the context.Get(r, name) value as an []string
func LastURLParameter ¶
LastURLParameter treats everything after the last slash (up until the question mark) as parameter-value
func MaxParallelism ¶
func MaxParallelism() int
MaxParallelism runs the maximum number of goroutines that should be created
func RemoveFromStringArray ¶
func ToFriendly ¶
ToFriendly converts a string to a HTML-friendly version. Replaces &, /, and space. Trims dashes and slashes.
Types ¶
type CacheObject ¶
type CacheObject struct {
// Expires is the expiration-interval after which the object should be fetched again
Expires time.Duration
// Fetch is the function that retrieves the value from the source
Fetch func() interface{}
// contains filtered or unexported fields
}
func NewCacheObject ¶
func NewCacheObject(exp time.Duration, f func() interface{}) CacheObject
func (*CacheObject) Val ¶
func (o *CacheObject) Val() interface{}
Val fetches the actual value from source using the Fetch function - only when needed.
type CacheStorage ¶
type CacheStorage struct {
// contains filtered or unexported fields
}
func NewCacheStorage ¶
func NewCacheStorage(cacheDir string) *CacheStorage
func (*CacheStorage) Add ¶
func (c *CacheStorage) Add(urlPath, requestUrl string)
func (*CacheStorage) Delete ¶
func (c *CacheStorage) Delete(urlPath string)
func (*CacheStorage) Exists ¶
func (c *CacheStorage) Exists(urlPath, requestUrl string) bool
